Mohamad: have you found a solution - how to use Unicode/UTF-8 with Win32::GUI?

please show me a sample of get utf8 character from AddTextfield() and print it it ,IDE

Please show me yours, the one that doesn't work (as per How (Not) To Ask A Question)

my database connection and others setting is correct

Well thats not what your error message is saying. Your text isn't encoded properly, so go ahead and encode it like A UTF8 round trip with MySQL explains that you need to.
